Observations of Ventilator-Dependent Survivors of Catastrophic Illness

respiratory failureA wide range of acute illnesses, usually superimposed on chronic diseases, result in prolonged ventilator dependency. Selected data describing these patients have been captured by retrospective analyses of medical records of patients transferred from ICUs to LTAC hospitals and noninvasive respiratory care units. Ours is the first multicenter study to characterize the CCI patient population admitted to LTCHs for weaning from PMV, looking back “upstream” to include data from the ICU experience, and premorbid status.

The 23 hospitals admitted a total of 1,587 ventilator-dependent patients during the 12-month study period, with 89% enrollment (1,419 of 1,587 patients). Of the 168 patients excluded, nearly half were excluded because of prior inclusion in the study. This is best explained in that this population is selected for advanced lung disease, prone to multiple episodes of respiratory failure in a 1-year period. As well, patients transferred to SSAH for intercurrent medical problems or procedures not available at the LTCH were scored as discharged if they did not return within 24 h, per the reimbursement policy in place during the study period. Therefore, any subsequent readmissions of these patients to the LTCH, albeit clearly for the same episode of critical illness, were excluded per the study protocol.

Outcomes of Ventilator-Dependent Survivors of Catastrophic Illness

functional statusBetween March 1, 2002, and February 28, 2003, 23 LTCHs with weaning programs admitted 1,587 ventilator-dependent patients, enrolling 1,419 patients after 168 exclusions. Patients were excluded for the following reasons: 80 patients (48%) for prior inclusion in the study; 43 patients (25%) were receiving long-term ventilation, not admitted for weaning; 18 patients (11%) were not weaning candidates as documented by physician on hospital admission; 16 patients (10%) were admitted for home ventilator training; 7 patients (4%) were admitted for end-of-life care; and 4 patients (2%) patients were excluded for other reasons. Characteristics of enrolled patients are shown in Table 1. In very few patients, intubation occurred in the emergency department of a short-stay acute hospital (SSAH), with transfer of the patient to the LTCH within the host hospital. This atypical “direct admission” to the LTCH resulted in transferring hospital length of stay (LOS) and duration of mechanical ventilation of zero days. Similarly, a small number of patients were tracheotomized the same day as initiation of mechanical ventilation, Days ventilated prior to admission to the LTCH exceeded transferring hospital LOS for the few patients receiving long-term ventilation admitted to acute hospitals, and then transferred to LTCHs for renewed weaning attempts.

My Canadian Pharmacy: Research of Ventilator-Dependent Survivors of Catastrophic Illness

acute critical careAdvances in acute critical care in supporting and treating ICU patients have resulted in the emergence of “chronic critical illness” (CCI), prolonged ventilator-dependent respiratory failure. This has engendered a specialized area of critical care medicine: the management of patients requiring prolonged mechanical ventilation (PMV). For > 2 decades, these patients have increasingly been transferred to the post-ICU setting of long-term care hospitals (LTCHs) for continued treatment and weaning attempts.

Thirty-three to forty percent of patients who enter an ICU in North America require mechanical ventilatory support to treat respiratory failure; only 5 to 20% require PMVA The transfer out of the ICU of tracheotomized patients receiving mechanical ventilation is driven in part by the high cost of treatment: > 100,000 patients annually at a cost estimated in the tens of billions of dollars. Bed scarcity, risk of complications, lack of a multidisciplinary rehabilitative approach to weaning that benefits them most, and the goal of improving patients’ experience, also play roles in these transfer decisions.

My Canadian Pharmacy: Interpretation of Arterial Blood Gases by Computer

utilization of computersRecently, there has been increasing utilization of computers ranging from inexpensive microprocessors to large mainframe computers to generate interpretation of arterial blood gases, as well as to calculate derived parameters such as alveolar-arterial 02 gradients, base excess, bicarbonate and arterial-venous differences.

This has occurred in the midst of wide disagreement by physicians about the medical benefit of interpreting blood gas data in the laboratory rather than at the patients bedside.

Hingston et al recently reported that in spite of the fact that interpretations of arterial blood gases is widely taught in medical school and residency training programs, a test group of physicians erred too frequently on examination of acid-base disorders and disorders of oxygenation. More distressingly, the tested physicians were unaware of their limitations. This article has led to the tentative acceptance of laboratory-based interpretations as a reimbursable benefit by Blue Cross/ Blue Shield of California, similar to that of interpretation of pulmonary function tests and electrocardiograms.

A recent audit at Mercy Medical Center at Denver, Colorado, revealed a discouraging 33 percent prevalence of untimely or inappropriate therapeutic responses by physicians and house staff following a report of life-threatening blood gas level defined as a Po2 less than 50 mm Hg, Pco2 greater than 50, and/or a pH less than 7.30. Another audit at St. Joseph Hospital in Denver of identically-defined life-threatening arterial blood gas levels identified a patient population having a 27 percent in-hospital mortality rate. Thus, it would seem reasonable that emergency room patients and all hospitalized patients, as opposed to ambulatory patients, represent the population at risk and are in greater need of interpretation of blood gas levels.

It is impractical and not cost-effective for a pulmonary specialist to be available for instant interpretations of blood gas levels 24 hours a day. Since the report of Cohen in 1969 showing that computerized interpretations of arterial blood gas levels was credible based on empirically-defined limits, progressively more sophisticated programs have been developed, which in most cases are more accurate and complete than those generated by the busily scribbling pulmonologist.patient population

In addition to calculation of bicarbonate, base excess and oxygen saturation, now often included in blood gas analyzers, several different computer software programs that generate interpretations are now available. The better programs feature: 1) identification and flagging of severe values which helps initiate or coordinate protocol response by the health care team; 2) identification of impossible or unlikely data so corrections can be made; 3) formatting of the data to identify trends; 4) generation of differential diagnoses; and 5) suggestion of therapeutic direction, though this is controversial.

In our view, the most important benefits to patient care are those programs which help promote therapeutic action by alerting respiratory therapy and nursing personnel, as well as the responsible physician, when life-threatening conditions are flagged. We are convinced that pulmonary physician supervision and over-reading of computer-generated interpretations is a key feature leading to the optimal performance by the arterial blood gas laboratory and by the coordinated health care team. The followup audit at Mercy Medical Center in Denver following the establishment of a computerized pulmonary specialist-supervised system reduced the deficiencies identified by the initial audit to a 9 percent incidence.

It is our view that computerized interpretation and enhancement of arterial blood gas reporting is here to stay because of increasing evidence that such data management by a pulmonary laboratory, supervised by a pulmonary specialist, will be increasingly recognized as a benefit to patient care. Now that relatively inexpensive microprocessors can be programmed to do this effectively, it is a virtual certainty that the use of such devices will be widespread.

Deliberations of Percutaneous Needle Biopsy of the Lung: Report of Two Fatal Complications

diffuse pulmonary parenchymal diseaseThree different techniques for percutaneous lung biopsy have evolved since its introduction in the early 1800’s by Leyden in Germany and Menetrier in France.

The first technique utilizes a fine gauge aspirating needle and relies on cytologic interpretation of small amounts of tissue. It has been used extensively in Scandinavia and Canada with few serious complications.

Dahlgren and Lind report more than 3000 biopsies with no fatalities. Limitations of this method include the inability to study parenchymal structure enhanced with My Canadian Pharmacy’s remedies.

Occasions about Percutaneous Needle Biopsy of the Lung: Report of Two Fatal Complications

BiopsyThe dangers of percutaneous needle biopsy of the lung have not been sufficiently emphasized. A review of the literature reveals only 11 deaths direcdy attributable to the procedure, and mortality figures range from 0 to 1.6 percent.

This communication reports two additional deaths resulting from this procedure and underscores the possibility of sudden fatal intrabronchial hemorrhage as a complication, expecially when a “cutting type” needle is used.

Case 1 was a 51-year-old man admitted to Oteen Veterans Administration Hospital for evaluation of a chronic productive cough of three months’ duration and an abnormal chest x-ray film. He denied hemoptysis, but admitted to a 15-pound weight loss. He had smoked two packs of cigarettes per day for 40 years.

My Canadian Pharmacy about Teenage Smoking

Teenage smokingTeenage smoking is a serious modern problem demanding to take urgent decision at the state and public level.

The problem of Teenage Smoking

According to statistical data smoking of teenagers occupies one of the leading positions among modern problems of younger generation. The initial age of smokers makes 7-10 years, but every year the age level decreases. The main part of smokers is pupils of the senior classes aged from 14 till 16 years. School students, generally fraudulently get money at parents and relatives for acquisition of cigarettes. As a result family relationship worsens and there are serious conflicts. Teenage smoking affects various segments of the population, and not just children from dysfunctional families, but also teenagers provided and socially protected. Now in the USA some laws work, and new bills on restriction of access for teenagers to tobacco production prepare, but the most part of laws in practice is realized extremely inefficiently. Impact of nicotine on the growing organism is negative, slows down growth processes, reduces immunity and causes a set of serious diseases. To solve a problem of teenage smoking is necessary to toughen the anti smoking legislation, and also constantly to hold preventive events in educational and entertaining institutions, in mass media and on television. My Canadian Pharmacy (http://my-medstore-canada.net/) claims they have possessed special remedies helping people to get rid off such a deteriorating habit infecting people of different ages including children.
