Tuberculosis was on the decline from the mid 1950s until the mid 1980s; however, the United States is now experiencing a resurgence of tuberculosis. In 1992, approximately 27,000 new cases were reported, an increase of about 20 percent from 1985 to 1992. Not only are tuberculosis cases on the increase, but a serious aspect of the problem is the recent occurence of outbreaks of multidrug resistant (MDR) tuberculosis, which poses an urgent public health problem and requires rapid intervention.
Control programs involve two major components. First, and of highest priority, is to detect persons with active tuberculosis and treat them with effective antituberculosis drugs, which prevents death from tuberculosis and stops the transmission of infection to other persons. Treatment of active tuberculosis involves taking multiple antituberculosis drugs daily or several times weekly for at least six months. Failure to take the medications for the full treatment period may mean that the disease is not cured and may recur. If sufficient medications are not prescribed early and taken regularly, the tuberculosis organism can become resistant to the drugs, and the drug resistant tubercuosis then may be transmitted to other persons. Drug resistant disease is difficult and expensive to treat, and in some cases, cannot be treated with available medications.
The second major goal of control efforts is the detection and treatment of persons who do not have active tuberculosis, but who have latent tuberculosis infection. These people may be at high risk of developing active tuberculosis. The only approved treatment modality for preventive therapy requires treatment daily or twice weekly for a minimum of six months, and many patients do not complete the full course of therapy. Public and patient programs are needed to increase the awareness of the problems associated with tuberculosis control.
The study is part of the NHLBI initiative "Behavioral Interventions for Control of Tuberculosis" . The concept for the initiative originated from the National Institutes of Health Working Group on Health and Behavior. The Request for Applications was released in October, 1994.
The project, based on social learning theory, was conducted in several phases. First, a process evaluation of the current contact investigation process was conducted. Results guided the development of a revised contact investigation protocol, a software program for notebook computers designed to enhance protocol implementation, and a behavioral intervention to educate contact investigators in the use of the protocol and software. A formative evaluation of the intervention, protocol, and software was used to refine the procedures, which were then implemented throughout the State of Alabama. An impact evaluation was then conducted to assess the effectiveness of the procedures. If the impact evaluation results weresatisfactory, the behavioral intervention and contact investigation procedures would be developed in a format that could be exported to other areas and settings.

A diverse group of lung diseases that affect the lung parenchyma. They are characterized by an initial inflammation of PULMONARY ALVEOLI that extends to the interstitium and beyond leading to diffuse PULMONARY FIBROSIS. Interstitial lung diseases are classified by their etiology (known or unknown causes), and radiological-pathological features.
Pathological processes involving any part of the LUNG.
Any disorder marked by obstruction of conducting airways of the lung. AIRWAY OBSTRUCTION may be acute, chronic, intermittent, or persistent.
A condition characterized by infiltration of the lung with EOSINOPHILS due to inflammation or other disease processes. Major eosinophilic lung diseases are the eosinophilic pneumonias caused by infections, allergens, or toxic agents.
Increased VASCULAR RESISTANCE in the PULMONARY CIRCULATION, usually secondary to HEART DISEASES or LUNG DISEASES.
