Informed consent: a socio-legal study.

INTRODUCTION: Informed consent [IC] is a recognized socio-legal obligation for the medical profession. The doctrine of IC involves the law, which aims to ensure the lawfulness of health assistance and tends to reflect the concept of autonomy of the person requiring and requesting medical and/or surgical treatment. Recent changes in the health care delivery system and the complex sociological settings, in which it is practiced, have resulted in an increase in judicial activity and medical negligence lawsuits for physicians. While IC is a well-established practice, it often fails to meet its stated purpose. In the common law, the standard of medical care to disclose risks has been laid down by the Bolam test- a familiar concept to most physicians, but it has been challenged recently in many jurisdictions. This paper aims to discuss some important judgments in cases of alleged medical negligence so as to familiarize doctors regarding their socio-legal obligations. We also propose to discuss some factors that influence the quality of IC in clinical practice. METHODS: Literature review. RESULTS: The law of medical consent has been undergoing changes in recent years. Case law appears to be evolving towards a more patient centered standard of disclosure. Patient's expectations are higher and they are aware of the power of exercising their rights. Failure to obtain IC is one of the common allegations in medical malpractice suits. CONCLUSION: The medical professionals need to change their mindset and avoid claims of negligence by providing information that is "reasonable" in the eyes of the court.

Blood pressure control among diabetic hypertensives under cardiology follow-up at a regional hospital in rural Malaysia.

Three hundred thirty-one consecutive patients presenting with hypertension to the outpatient medical clinic of Tengku Ampuan Afzan Hospital, Kuantan, Malaysia were screened and 150 patients with concurrent diabetes were enrolled into a cross-sectional study. The majority of patients were male (60.6%) with a mean age of 60.0 +/- 11.0 years. The mean systolic blood pressure (SBP) was 140.9 +/- 20.1 mmHg and the mean diastolic blood pressure (DBP) was 81.7 +/- 9.8 mmHg. Only 38.0% (57/150) of patients had blood pressures within recommended guidelines (130/80 mmHg). The mean blood pressure in this group was 123.7 +/- 8.5/76.4 +/- 5.6 mmHg. The majority of patients were on either 2 (41.3%) or 3 (31.3%) anti-hypertensives. Females had a significantly higher SBP 145.4 +/- 22.7 vs. 138.0 +/- 17.8 mmHg in males (p = 0.026). The level of blood pressure control in diabetics was unsatisfactory, especially in females and the elderly. A reassessment of priorities in the management of patients with concurrent hypertension and diabetes is therefore, urgently needed.

Risk factors for anti tuberculous drugs induced hepatitis: a prospective survey from a chest clinic in a general hospital.

A prospective survey on 14 consecutive cases with tuberculous drug induced hepatitis was done at our chest clinic in a state general hospital over a period of 15 months. There were 30 controls chosen randomly from the chest clinic register. The cases had lower mean body mass index (P<0.008), serum albumin (P<0.005) and higher serum globulin (P<0.04). Serum liver transaminases and total bilirubin rose significantly during the acute episode of drug induced hepatitis. Among the risk factors studied, only chronic hepatitis B carrier status was found to be more prevalent among the cases. There was one death (7.1%) over the whole study period.

Usefulness of cytological specimens from bronchial brushings and bronchial washings in addition to endobronchial biopsies during bronchoscopy for lung cancer: 3 years data from a chest clinic in a general hospital.

A retrospective review of all bronchoscopy cases for investigation of lung cancer between January 1997 and December 1999 was done. The cases were included if endobronchial mass was visible (Group A) or when there was an abnormal mucosa and/or bronchial narrowing in the absence of a mass (Group B). All patients in Group A (n = 177) underwent endobronchial biopsy (EB) bronchial brushings (BB) and bronchial washings (BW). All cases in Group B underwent transbronchial biopsy (TBB), BB and BW. Only a small increase in the positive results for cancer was seen when cytology specimens (BB and BW) were added to EB (85.3% vs 88.1%, McNemar's P = 0.06) in Group A but there was a significant increase in Group B (37.3% vs 54.2%. McNemar's, P = 0.001). Therefore although cytology specimens did not significantly add to overall yield of positive results when endobronchial lesions were visible, when mass lesions were not visible, cytology specimens increased the yield by 16.9%.
